Hi all,
I ended up creating a custom filter web part that was passing the PUID to SSRS report viewer web part in a project site.
Works perfectly fine until you save the site as a project site template. I attached the site template to an EPT and creating a new project. The project site created fine, but the connections between the custom filter web part and SSRS Report viewer web part is broken!
Paul gave me this web part to start with, but this doesn't work in SharePoint Integrate Mode: http://gallery.technet.microsoft.com/projectserver/Report-Viewer-webpart-439e0062
And SharePoint Integrated Mode is what we are pushing our clients towards.
Any help will be highly appreciated.
